abstract
Rock skippers (Istiblennius dussumieri) are important for their biological and ecological studies and used as potential indicator to investigate the ecological conditions of coastal waters. They are considered as an important tool for the environmental monitoring and assessments of coastal aquatic ecosystems. In this study we measured relative density of rock skipper at 3 sampling stations namely Haql, Sharmaa and Duba in varying environmental conditions of Tabuk during the year 2014. The results of this study showed a direct relation between relative densities of rock skipper in response to monthly variations in climatic conditions of Tabuk. Rock skippers are very sensitive to aquatic environmental conditions and their potential would help the researchers working on this species.
